SPE CIPICATION forming part of Letters Patent No. 374,082, datedNovember 29, 1887.

w Application filed May 29, 1885. Serial No. 167,008. (No model.)

To (ZZZ whom it may concern;

Be it known that I, JoHnPHILLIPs, of St. Louis, in the State ofMissouri, a citizen of the United States, have invented a new and use- 5ful'Improvement in Boot and Shoe Crimping Machines, of which thefollowing is a full,clear, and exact description, reference being had tothe accompanying drawings, forming a part of this specification, inexplaining its nature.

The principal object of the invention is to provide a crimping-machinewith crimpingjaws which move both vertically and laterally, so that itsaction upon the upper as it is presented to them shall be as nearly atright angles to the workingedge of the crimping frame or support asdesirable.

Another object of the invention is to provide the boot or shoe upper,while it is passing through the crimpingjaws, with a considerable extentof travel, so as .to stretch the leather in the right direction, and getas much corner, as it is termed, as possible without injury to thestock.

It also relates to various features of construction, all of which willbe hereinafter'm ore fully described.

Referring to the drawings, Figure 1 repre sents a front elevation of amachine containing my invention. Fig. 2 is a side elevation thereof.Fig. 3 is a plan view thereof. Fig. 4 represents a section upon the lineas m of Fig. 1, and a side elevation of the portion of the frame to theleft thereof. Fig. 5 is a section upon the line y 3 of Fig. 1. Fig. 6 isa section upon the line z z of Fig. 1. Figs. 7 and 8 are detail views.

A A are the side frames of the machine.

A is an upper cross-girth, and A a lower cross-girth, connecting the twoframes.

Bis a cross-head, carrying or supporting the crimping block or formb,which is removable therefrom.

The crosshead is adapted to be vertically reciprocated, and I willhereinafter describe one means of so moving it. This vertical movementof the cross-head moves downward the crimping form or block between thecrimping-jaws O between which is arranged a narrow space, into which thecrimp- 5o ing form or block with the upper thereon is enable thecrimping-form to present uppers of 100 piece, 0 secured to the upper endofthe wedge.

The side pieces, 0 c, are arranged in relation to the wedgesubstantially as shown in Fig. 1that 'is, their inner edges, a, bearupon the inclined surfaces 0* of the wedge c.

In other words, the wedge is between these two parts 0 c, and sodisposed in relation to them that its movement shall cause them to beseparated or brought together, according as the wedge moves, and withoutbreaking joints.

The working-faces of each jaw, comprising the face of the wedge 0 andthe faces or side surfaces of the parts a c, are upon the same line, orsubstantially the same line.

In the drawings I have represented the parts do of the jaws as supportedby thecross-piece D, which has the downward and outwardlyextendingsupports (1, in which are formed dovetail ways or recesses for thesupport of the parts a c, which have dovetail projections or tonguesentering said dovetail recesses. This construction is shown in sectionin. Fig. 6. I have also shown the wedges vertically movable in relationto the jaws O C, so that their upward movement shall cause the parts 0 cto be moved laterally, or away from each other; So and upon the downwardmovement of the wedges these parts are returned or moved toward eachother by the springs e e, the di-' verging movement of the parts a 0upon the upward movement of the wedges causing the 4 springs to becompressed. In lieu of this construction, the back sides of the wedgesmay be provided with grooves parallel with their inclined surfaces forthe reception of pins or rolls secured or fastened to the parts 0 c. Thec grooves will then act as guides in opening or moving apartand closingor drawing together the parts 0 0, according as the wedge is moved up ordown; and I would here remark that instead of moving the wedgevertically it may 5 be stationary and the parts 0' '0 made movablevertically in relation to it.

It is quite essential that the two jaws have a horizontally-yieldingmovement sufficient to u upper-leather of increased thickness.

varying thickness to the jaws without injury, and I have shown each ofthe supports'D and sections 0' c of the jaws as arranged to yieldhorizontally from each other. This construction is shown in Fig. I,whereFF represent the ends of the support D, and fthe holes or aperturesin the frame which receives and holds the ends. f are bearing-platesmoved by the springs f against the end portions of these pieces and actasa spindle to move them toward each other with a proper degree ofpressure, but not sufficient however, to prevent the parts D from beingmoved away from each other or separated upon the presentation to thejaws of It is of course essential that the guides also have the sameyielding movement; and this is pro vided in substantially the same wayby means of the spring-held bearing-plates G G, (see Fig. 5,) thebearing resting against the outer surfaces of the wedges c 0, (see Fig.5,) 9 representing the supports for the springsg",which press againstthe bearingplates. I may, how ever, use any other equivalent yieldingsupports for the jaws.

The wedges c are supported by the cross head H, and it and thecross-head B are movable to and from each other by the following means:The cross-head B has secured to each end the rack I), which extendsdownward to en gage with the teeth of the pinious b operated by thegears Z) upon the shaft 1). The crosshead H has attached at each end theracks h, the teeth of which are adapted to engage with the teeth of thegears I). It is necessary, however, that the cross-head Bcommence tomove before the cross-head H and the wedges, in order that the upper maybe well within or between the two jaws before the side pieces orsections, 0 c, of the jaws are caused to exert their special action; andin order that this may be accomplished, I have arranged each of theracks h to be held away from the gears If" until the piuions I) havemoved the cross-head B sufliciently to bring the crimping-form b betweenthe jaws O U. \Vhen this has been done, the rolls h, carried by the armsh", extending from the racks I), come in contact with the inclines hupon the upper outer surfaces of the racks h, and, riding thereon, drawthe racks h inward or toward the racks b and cause the teeth of theracks h to engage the teeth of the gear b This starts the operation ofthe wedges, and they are moved upward while the crimping-form is yetmoving downward, and the sections 0 0 of the jaws are thus caused tomove outward and thereby exert upon the portions of the upper againstwhich they are brought in contact a wiping and feeding action from theedge of the crimping-form inward. This movement continues until theentire upper has been subjected to the fitting or crimpingmanipulations, and the travel of the cross-head and jaws in relation toeach other is such that the entire area of the upper is subjected to thecrimping and stretching action of the jaws.

The relative movements of the upper crosshead, B, and lower cross-head,II, in relation to each other may be varied,as desired. Upon the end ofthe respective movements of the cross-heads the machine comes to rest,and is then reversed, and upon the rolls h leaving the inclines If theracks h are automatically drawn from their operating-gears I) by meansof the springs and lug 7a, which fits the dove tail or other recess inthe racks, which allows or permits the movement of the racks in relationto it. These lugs k are moved outward by the springs k.

I prefer that the surfaces of the jaws be provided with corrugationsextending from the central line of the wedge-sections downward; but asthis feature is common to other crimping'machines, I make no claim toit.

I would state that in lieu of making the wedges c movable they may bestationary, and the supports D and sections 0 c of the jaws mademovable, and in the same time and in the same direction with thecrimping block or frame. This construction is advisable when it isdesirable to have a slow and long wiping and feeding action of the jawsO O. The frame and the jaws may be moved downward by contact with thecross-head A therewith, or by independent mechanism.

It is not necessary that each set ofjaws C C and each of the wedges 0have lateral movements in relation to each other, as for certain kindsof work it will answer if only one set be provided with this adjustment.

Having thus fully described myinvention, I claim and desire to secure byLetters Patent of the United States 1. In a crimping-machine, thecombination of the crimping form or frame with the crimping-jaws havingthe laterally-movable sections a c, all substantially as and for thepurposes described.

2. In a crimpingmachine, the jaws G 0, having the movable sections a cand the operating-wedges c, all substantially as and for the purposesdescribed.

3. The combination, with the cross-head D, having the supports (1, ofthejaws having the laterally-movable sections 0, sliding in said supports,the wedges c, and the springs 0, substantially as set forth.

4. In a crimping-machine, the combination of the vertically-movableframe or form Z1, jaws having sections 0 c, and the operatingwedges 0,adapted to have movements in relation to each other, as specified, allsubstantially as and for the purposes described.

5. The combination of the crimping form or frame I), the jaws O 0,having the movable parts 0 c, and the wedges 0, adapted to be broughtinto operation after the frame or form I) has moved between the jaws,all substantially as and for the purposes described.
